ELECTRIC HAIR COMB AND HAIR STRAIGHTENING MEANS Filed Feb. 18,1932

H- GAndePs on INVENTOR- ATTORNEY- ELECTRIC HAIR 001m; AND HAIR"STRAIGHTENINGMEANS Patented Nov. 28, 1933 This invention relates to newand useful im-' provements in electrically heated combs used forstraightening curly hair. j'

v It is'a well known human weakness that those who have straighthairoften like to have'their hair artificially curled, while those who havevnaturallywavy hair are sometime desirousof'.

having their hair straight. Tosatisfy the desire of the latter classthere are available electrically heated combs for straightening curlyhair.

The combs of this type now available aremade of some metal to resistheat, and provision is made to heat them electrically by means of aheating I I element housed in the hollow upper part of the comb.

When using this appliance, small portions of p the hair are firstsmoothened out by means of the teeth of the comb, and when the hair isin the desired conditionof smoothness heat is applied to it in order tofix and make lasting the smoothness previously obtained.

Such use of the present devices is not without inconvenience to theuser, since the teeth of the comb form one body with the part containingthe heating element, due to which the teeth attain approximately thesame temperature as the hollow partcontaining the heating element.Accordingly, there is danger of burning the scalp with the hot teeth ofthe comb,

and the user cannot properly smoothen the hair.

before applying the heat.

My present invention obviates the difficulty described in the foregoingby thermally insulating the part containing the heating element from theteeth of the comb. With this arrangement the upper part of the comb mayattain a high temperature without appreciably heating up the teeth, andthus the user may effectively smoothen the hair with the teeth of thecomb before applythe heat for securing an approximate permanency of thecondition ofthe hair thus arranged or straightened out.

Another advantage of the arrangement dis- 7 closed in this invention isthat the comb proper is easily detachable from the rest of theappliance, thereby facilitatingsterilization of the said comb. This is aparticularly desirable feature in barber shops or beauty parlors wherethe same device may be used by a largenumber of customers.

With the above and other objects in view, this invention consists of thenovel features of construction, combination and arrangement of parts,hereinafter fully described; claimed, and illus- -trated in theaccompanying drawing forming characters. 'of reference ind icatecorresponding parts in all views, and in which;

In the accompanying illustrations 11 is a hollow housing, and insidethis housing, electrically insulated therefrom, there is arranged a.

heating element 12. is connected to a source-of current by means of acord 13,-and the flow of current can be-con-v trolled by means of atumble switch 14 housed: in the handle 15 of the device. 15' is hollowedout for the purpose therein part of the cord 13.

The said heating element The said handle ofconcealing A collar 16 isfastened to the handle 15, the said collar being formed with aprotruding, substan- -tially square part 17. The comb properbears the Jnumeral 18, and it is supported by an-offset stem 0 -1' 19. The end ofthe said'stem is inserted into the square part 1'7 of the collar 16, andthe c'onnec tion between the stem and the handle is completed by meansofthevmachine screw 20 which is vthreadedly connected to the collar 16.With this arrangement the comb part can be easily detached or attachedto the handle for sterilization.

There is an air space 21 between'the housing:

heating element and the comb proper has to take placeby radiation-andnot by convection as'is With this arrangement there will be a' considcontaining the heating element and the comb,

clue to which any heat transmission betweenthe erable difference betweenthe temperature of the housing 11 and the comb proper, therebygreatlyincreasing the usefulness of the appliance, and at the same timeeliminating the danger of burning the users scalp. v At the time whenthe appliance is being put into use it may be desirable to heat uprapidly the comb proper to a moderate temperature. To achieve this end ametallic spacer 22 shown in Fig. 2 may be inserted into the space 21,the di- 05"- the 110.

, hand surface-'of'the housing 11 coming intocontact with the scalp. Thepurpose of' this added protection is to shield the scalp when thecornbis laid upon the head with the concave side up as preferred by someusers.

It is obvious thatchanges may be made'in the form, construction andarrangement 'ofgthe' several parts, as shown, within the scope of theappended claims, without departingfrom thespirit of the invention, and Ido not, therefore, wish to limit myself to the construction andarrangement shown and described herein.

What Iclaim as new, and desire tosecure by Letters Patent of theUnited-States, is:

I 1. A device for straightening hair, comprising a housing.containing-an electric heating element and being-fastened'to a handle, acombattached to the latter by means of a. shank, and being thermallyinsulated: from the said'housing, the

teeth of the comb; having an upwardly extending portion shielding therear of thesaid housing.

I t 2. A device for straightening hair, comprisinga housing containingan electric heating element and being fastened to a handle, acombattached" to the latter bymeans of a shank, and being thermallyinsulated from the said housing, a

spacer adapted for insertion between the said housing andthe' combproper, the said spacer being provided with a lug, whereby to adjust the1atter.-

3. A device for straightening hair, comprising a housing containing anelectricvheating, element and being fastenedto a handle, a combattachedto the latter by] means of a shank, andbeing thermally'insulatedfrom'the said housing,-the back of the housing being provided with alarge convex surface, whereby to impart impressions upon. the hair;..

i 4. In adevice for straightening hair, the combination of an electricheating element, contained in a housing; with a comb arranged in spacedrelation to the: latter,. the said comb having an elongatedhandleattached to the said housing, and a spacer formed with a concave uppersurface and adapted for insertion betweenthesaid housing' andcomb'proper; 1

5. A device for straighteninghair, comprising}:
